So do you know how to get the glutton ending i am kinda confuse how to get it
There isn't an ending called Glutton, There is Truth, Gutslut, Rebirth, Soulless and Artifact.
Truth requires exhausting all conversation options and never choosing options that make you seem like willing prey.
Dialogue includes keep speaking to your mother at the basement door at the start, speak to Nala repeatedly when you first meet her in the Maid Bedroom, Speak to her there again after she rescues you from Mika for the first time. You must not find the ghosts interesting, you have to be frightened so you can choose the resist options when needed. When Nala asks if the worst happens what you would do say you would try save her. Do all of this should be enough that you take the rebirth route as usual but this time you continue playing for a bit longer, though the puzzles are the same as the gutslut route at that point, the dialogue is different and the ending is different.
